If cdxCmtsCmDMICMode is set to lockingMode(3), this object
would contain the restrictive QoS profile number as
indicated by docsIfQosProfIndex if set and it will
have 0 if not applicable or not defined. In case,
cdxCmtsCmDMICMode is set to lockingMode(3) and this
object is not defined then the CMTS defaults to special
QoS profile that limits the downstream and upstream
service flows to a maximum rate of 10 kbps. However,
for this to happen the modems should have the
permission to create QoS profile.
